I don't think Kidd was done in by railgun explosion + DD combo. He got rekt by DD only.
Railgun was getting charged but thing with such equipment or with any explosive material is they go off immediately when gets triggered or gets cut to be more specific to the context.
Here's the coloured version - we can clearly see railgun being cut in half with no explosion and Kidd getting directly hit by DD.
